Homebrew Desmume duplicate freeze screen

[SrBu]

Hi! I'm new here, and I want to ask you something about a bug that I have on all versions of Desmume.

When I maximize or minimize the window the game screen duplicate and bug it.

Any one know what I can do to solve this?

Okay I changed it from DirectDraw to OpenGL on Config > Display Method.
